-
(Geological Society of South Africa, 1999)One hundred and forty five grains of laurite in polished sections of samples from one borehole through the major chromitite layers and some chromite-bearing silicate rocks of the Lower and Critical Zones of the western ...
-
(Geological Society of South Africa, 1984-09)The Upper Triassic Molteno Formation of the Natal Drakensberg forms part of the upper Karoo Sequence. It rests with an erosional base on the Beaufort Group and has a gradational upper contact with the Elliot Formation. Four ...
-
(University of Pretoria, 2019)Faults and dolerite dykes within Basement- and Karoo-aquifers in northern Mozambique may increase groundwater occurrence but may also be barriers to groundwater flow. Should observation boreholes drilled into regional and ...
-
(University of Pretoria, 2017)A research project was undertaken to delineate aquifers in Beaufort West. Recent studies in the Karoo Basin utilised geochemistry indicators to differentiate between shallow and deep groundwater. The shale gas exploration ...
-
(Elsevier, 2018-06)The Junggar Basin is one of the most important basins for hydrocarbon production in China. Within the basin, the Chunfeng Oilfield forms one of the most important oilfields of the area. Despite the significant work that ...
-
(Elsevier, 2019-03)Recent studies have identified cemeteries as potential environmental reservoirs of multi-drug resistant pathogenic bacteria that could contaminate groundwater sources posing public health threats. However, these findings ...
-
(University of Pretoria, 2018)The high relief or mountainous basalt in and around the regions of Lesotho has extensive information on the nature and properties of the basalts, as a result of several developments on these basalts such as the Lesotho ...
-
(University of Pretoria, 2018)Water supply dams are essential infrastructural components, contributing to water security, ensuring economic growth. The construction of De Hoop Dam in South Africa is no exception. Water supply needs to keep abreast with ...
-
(University of Pretoria, 2017)The Cretaceous Zululand Basin is one of proposed areas for geological CO2 storage in South Africa. The knowledge of the basin is however very limited. This thesis aims to describe the sedimentary facies of the ZA core, ...
-
(SpringerOpen, 2018-09)Coal contains a significant concentration of free radicals as a result of the coalification process. One of the experimental methods sensitive to the presence of radicals is electron spin resonance (ESR), and differences ...
-
(Elsevier, 2018-02)The ability to accurately estimate systematic risk (or beta) in the presence of reference-day risk is an ineluctable requirement for all applications of the capital asset pricing model (CAPM). This research documents ...
-
(Springer, 2019-02)Implications of improved understanding of variably saturated flow are numerous, especially given the complexity, heterogeneity, and anisotropy of the intermediate fractured vadose zone. One such an implication is the ...
-
(Elsevier, 2018-09)The ∼2.23 Ga Hekpoort Formation (Transvaal sub-basin) and the ∼2.43 Ga Ongeluk Formation (Griqualand West sub-basin) represent voluminous Paleoproterozoic igneous events on the Kaapvaal craton of South Africa that predate ...
-
(Elsevier, 2018-07)Biophysical and socio-economic monitoring during unconventional oil and gas (UOG) extraction is important to assess change and to have reference conditions against which to identify UOG extraction activity impacts. The ...
-
(Royal Society Publishing, 2017)Various biophysical and socio-economic impacts may be associated with unconventional oil and gas (UOG) extraction. A vulnerability map may assist governments during environmental assessments, spatial planning and ...
-
(Elsevier, 2018-12)The nature of letsoku and related clayey soils, traditionally used by indigenous Southern African communities for a wide range of purposes, was explored. Thirty nine samples were collected from Botswana, Lesotho, Swaziland, ...
-
(Springer, 2017-12)The thickness of the crystal mush on magma chamber floors can be constrained using the offset between the step-change in the median value of dihedral angles formed at the junctions between two grains of plagioclase and a ...
-
(International Union of Geological Sciences, 2017-06)The proceeds of the illicit trade in precious metals are used as currency to pay for, for example, other illicit goods and support terrorism. Precious metals are often mined in less developed countries and exported to ...
-
(University of Pretoria, 2018)Slope design and mining in foliated in-situ rock masses can be a major logistical and geotechnical hindrance. The Rock Mass Classification parameters need to be considered in relation to the anisotropic rock masses. What ...
-
(University of Pretoria, 2015)Adequate knowledge of the regional subsurface geometry depth relationship between the limbs and distribution of mineral zones within the Rustenburg Layered Suite (RLS) is required for better understanding of the emplacement ...
